I think the problem is, people expect home construction materials and construction methods in an RV. They are not, never have been, and I doubt they ever will be.
If you expect a tiny home, just Google the price of one. They built them all the time, there is even a TV show dedicated to them.
RV's are built to a price point. They build what will sell. Materials and construction techniques improve but they are still assembled at a rate and quality level consistent with the selling price.
In general the more you pay the better the product but not always.
